[0041] See attached document Figures 1 to 2 As shown, this application provides a pulp recycling device, including...
[0042] The device includes a housing 1, a filter assembly, and a vibration assembly. The filter assembly is located inside the housing 1 and is used to filter the pulp liquid. The vibration assembly is used to drive the filter assembly to vibrate up and down repeatedly to prevent the pulp from accumulating on the surface of the filter screen 802 during the filtration process, which would cause the filter screen 802 to become clogged and affect the filtration effect.
[0043] Specifically:
[0044] like Figure 4 As shown, the device housing 1 is enclosed on all sides except for the open top. A partition 2 is installed inside the housing 1, located closer to the bottom, but with a space between them. The partition 2 divides the housing 1 into upper and lower sections. The lower section is the filtrate chamber 101, where filtered pulp enters. The filtrate chamber 101 is equipped with an outlet pipe 10, which discharges the filtered pulp to the next process stage. An electromagnetic valve (not shown) is installed on the outlet pipe 10 to control the discharge of the pulp. The upper section is the filter chamber 102, where the pulp is filtered. A connecting hole 3 is centrally located on the partition 2. A pulp channel 4 is located above the connecting hole 3 within the filter chamber 102, and the pulp channel 4 is welded and fixed to the inner wall of the housing 1 via a fixing plate 5. The top of the device housing 1 is provided with a flip-up top cover 15. The top cover 15 is provided with a handle 17 for easy lifting. The top cover 15 is provided with a filling port 16 corresponding to the pulp channel 4. The filter assembly is set in the connecting hole 3 and forms an insertion relationship with the pulp channel 4 to move up and down in the vertical direction. The pulp to be filtered is added from the filling port 16 and flows into the filter assembly along the pulp channel 4.
[0045] In the above, such as Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the filter assembly includes a filter box 6 and a filter cylinder 8. The filter box 6 is located within the connecting hole 3, and the filter box 6 and the connecting hole 3 are slidably connected. The filter box 6 is vertically continuous, and a slot 7 is provided on the top surface of the filter box 6. The bottom end of the pulp channel 4 is inserted into the slot 7. The slot 7 has a certain depth, and the pulp channel 4 remains within the slot 7 during the vertical movement of the filter box 6. An annular platform 18 is integrally formed on the inner wall of the filter box 6, and the filter cylinder 8 is placed on the annular platform 18. Thus, the pulp flows into the filter box 6 from the pulp channel 4 and is filtered through the filter cylinder 8.
[0046] The filter cartridge 8 includes a cylinder 801 and a filter screen 802. The cylinder 801 is placed inside the filter box 6 and supported by a ring platform 18. The filter screen 802 is fixedly installed inside the cylinder 801. To ensure that the filter cartridge 8 and the filter box 6 complete the up-and-down amplitude movement together, in a preferred embodiment, such as... Figure 2 and Figure 3 As shown, the cylinder 801 is fixed to the filter box 6 by a fastener 9. Specifically, the fastener 9 includes a first handle 901 and a second handle 902, each consisting of a set of two. The first handle 901 is integrally formed on the top surface of the cylinder 801 and is symmetrical to each other. The second handle 902 is integrally formed on the top surface of the filter box 6 and is symmetrical to each other. The top surface of the cylinder 801 is flush with the top surface of the filter box 6, and the first handle 901 and the second handle 902 are correspondingly arranged. The second handle 902 is provided with a damping rotation hook 903, which can be engaged and disengaged from the first handle 901 by rotation. As can be imagined, by fastening the first handle 901 and the second handle 902 together with the hook 903, since the hook 903 is a damped rotation, the filter cylinder 8 and the filter box 6 are fixed to each other without external force, and the two move up and down in sync. At the same time, by rotating the hook 903 to separate it from the first handle 901, the filter cylinder 8 can be taken out from the filter box 6, and the pulp accumulated in the filter cylinder 8 can be poured out for maintenance of the filter assembly.
[0047] In the above, to achieve damped rotation of the hook 903 on the second handle 902, as follows: Figure 3 As shown, the hook 903 is integrally formed by the bushing and the hook body. The bushing is rotatably mounted on the second handle 902. Compression springs 904 are provided at both ends of the second handle 902. The compression springs 904 clamp the bushing and apply resistance to the bushing, so that the hook 903 can only rotate when subjected to a large external force.
[0048] In this embodiment, to achieve the up-and-down amplitude movement of the filter component, such as Figure 2As shown, extension plates 11 are symmetrically arranged on both sides of the filter box 6, and the vibration assembly is connected to the extension plates 11. The vibration assembly includes a vibration spring 12, an eccentric cam 14, and a vibration motor 13. The vibration spring 12 is fixedly connected between the extension plate 11 and the partition plate 2. The eccentric cam 14 is disposed on the extension plate 11. The vibration motor 13 is fixedly disposed on the device housing 1, and the eccentric cam 14 is fixed to the output end of the vibration motor 13. As can be imagined, when the vibrating motor 13 drives the eccentric cam 14 to rotate, the eccentric cam 14 gradually rotates from contacting the extension plate 11 at its short diameter end to contacting the extension plate 11 at its long diameter end. At this time, the filter assembly is pressed down, and the vibrating spring 12 is compressed. As the eccentric cam 14 rotates, the vibrating spring 12 gradually resets and lifts the filter assembly. Thus, with the continuous rotation of the vibrating motor 13, the filter assembly achieves periodic up-and-down amplitude movement, thereby preventing the pulp from accumulating on the surface of the filter screen 802 during filtration, alleviating pulp clogging of the filter screen 802, and accelerating the filtration effect.
[0049] As can be seen, the working process of the pulp recycling device provided in this application embodiment is as follows:
[0050] The pulp to be filtered is added through the filling port 16. The pulp flows into the filter cylinder 8 through the pulp channel 4. The vibration motor 13 is started, and the vibration motor 13 drives the eccentric cam 14 to rotate. The cooperation of the eccentric cam 14 and the vibration spring 12 makes the filter box 6 and the filter cylinder 8 complete a periodic up and down amplitude movement together. This prevents the pulp from accumulating on the surface of the filter screen 802 during the filtration process, alleviates pulp clogging of the filter screen 802, and speeds up the filtration effect. During the filtration process, the drain pipe can be opened to discharge the filtrate while filtering. When there is a lot of pulp remaining in the filter cylinder 8, the top cover 15 can be opened, the hook 903 can be rotated to separate from the first handle 901, and the filter cylinder 8 can be easily removed from the filter box 6 by holding the first handle 901. After pouring out the remaining pulp, the filter cylinder 8 can be put back into the filter box 6 to continue filtration.
[0051] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
